' GEARING.

Specification of Letters Patent.

Patented Jan. 23, 1912.

Application filed April 15, 1911. Serial No. 621,506.

To all whom it may concern:

Be it known that I, JOHN W. PEDIE, a citizen of the United States, and aresident of Souris, in the county of Bottineau and State of NorthDakota, have invented certain new and useful Improvements in Gearing, ofwhich the following is a specification, reference being had to theaccompanyingdrawmgs.

My invention relates to an improvement in convertible gearing, or one Iwhich is adapted to be applied to a manually operated machine to adaptthe same to be operated by power, and it has for its object theprovision of such a gearing which is adapted for attachment to thedriving shaft of such a machine, so that the same may be changed frommanually operated to power operated.

To the above end I provide a light simply constructed device which, forthe purposes of illustration, I have shown as attached to a fanning millof the usual form, in order that the hand operated crank by which suchmill is ordinarily driven may be removed and the same replaced by areadily attachable power operated gear.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and particularly pointed out in the appended claim, itbeing understood that changes in the specific structure shown anddescribed may be made within the scope of the claim, without departingfrom the spirit of the invention.

In the accompanying drawings forming a part of this specification, andin which like numerals of reference indicate similar parts in theseveral viewsFigure 1 shows a side elevational view of a fanning mill ofusual construction, provided with my attachment; Fig. 2 shows asectional detail of the attachment; Fig. 3 shows a detached detail ofthe dished housing as used in my invention.

In Fig. 1 of the drawing is shown a fanning mill of conventional form,including a set of rear standards, a set of cross braces and a drivingshaft, the latter being provided with an eccentric engaged by a pitmanhaving at its outer end a rocking bar, the upper end of which isconnected with the sieve to agitate the same, all as is usual in fanningmill constructions.

The fanning mill of the form shown is, as a rule, operated by means of acrank by which the shaft is rotated. My present invention is directed toproviding the shaft of a fanning mill or other hand driven machine Witha readily attachable power-driven mechanism. To this end the eccentricand crank are removed from the shaft, and in place of the former, nextto the bearing 4, I secure a chain gear 5 by means of a key. Next to thechain gear 5 is secured the eccentric 6 in order that the rock bar 7 maybe upon the outside. The shaft 8, in certain constructions of fanningmills, is located near the rear standards 9, and to one of thesestandards I secure a peculiarly constructed dished housing 10 having theapertured securing ears 11 and the outstanding bearing sleeve 12. Bymeans of suitable screws X, the housing 10 is secured to the standard 9.

Revolubly held within the outstanding bearing sleeve 12 is a stub shaft1 1. The shaft 1 1 is provided with a stop collar 16 working against theinner surface or end of the sleeve 12, and forming a part of this stopcollar 16 is the chain gear 17. The thickness of the chain gearand stopcollar, as shown in Fig. 3, is such that the outer face of the chaingear 17 rotates and is held immediately adjacent to the standard 9. Adrive pulley 18 of a size somewhat greater than the chain gears, whichare of like sizes, is secured to the outer end of the stub shaft bymeans of the key 19 as shown.

The gears 5 and 17 having been properly secured in alinement, a suitabledrive chain 20 is connected and passed over the same. A suitably drivendriving belt 21 is then brought into connection with the pulley 18. Theforward chain gear and the housing 10 can be readily placed in positionon a fanning mill or other hand operated mechanism,

so that the same can be quickly changed to a power-driven machine, andthe attachment is simple and comparatively inexpensive in construction.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

In a mechanism for converting a machine driven by a hand crank -into amachine driven by power, the combination with a gear adapted to be keyedto the driven shaft of the machine, of a housing comprising a dishedportion having ears extending therefrom by which the housing is adaptedto be secured in position on the machine, a-bear ing sleeve extendingoutwardly from the dished portion, a short shaft rotatably mounted insaid sleeve, a pulley fast to the outer end of the short shaft adaptedtobear against the outer end of the sleeve, a collar mounted on theshortshaft Within the dished portion, and adapted to bear against the innerface of the dished portion, a gear mounted on the inner end of saidshort shaft,

and a chain adapted to connect the gear on 10 said short shaft to thegear'on the driving shaft. 7 In testimony whereof, I affix my signature,in presence of tWo Witnesses.
